黄金冶炼焙烧烟气中砷的回收

Arsenic recovery from roasting fumes of gold smelting

采用二段焙烧法对含砷复杂金精矿进行预处理,且回收烟气中的As2O3。通过潼关中金冶炼有限责任公司生产实践,介绍了黄金冶炼焙烧烟气中砷回收的工艺,分析了砷回收系统的设备特点、操作技术条件以及重要的技术参数,为含砷金精矿预处理工艺的环境保护提供了科学依据。

Complex gold concentrates are pretreated with the two-staged roasting method,and As2O3 in the fume is recovered.By the practice of Tongguan China National Gold Smelting Co.,Ltd.,the process of recovering arsenic from roasting fumes of gold smelting is introduced.During the introduction,the equipment characteristics,operational conditions and technical parameters that matter of the recovery system are analyzed,providing scientific basis for the environmental protection work through pretreatment of arsenic-containing gold concentrates.
